F = 3/r.
The formula for the volume of a cylinder is
V=πr²h. We know that h=2r, so this gives us:
V = πr²(2r) = 2πr³
The surface area of a cylinder is the sum of the areas of all of the faces. The bottom and top are circles, whose areas are both given by A=πr². The lateral area of a cylinder is given by the circumference multiplied by the height. C = 2πr, and the height is 2r, so the lateral area would be
A=(2πr)(2r)= 4πr². This gives us a total surface area of
SA = 4πr²+πr²+πr² = 6πr².
The ratio of surface area to volume would be:
SA/V = 6πr²/2πr³. After simplifying, we have f=3/r.
Answer:
y = -2x + -3
Step-by-step explanation:
The line has a slope of -2 because when counting from point to point, its 2 down and one over; 2/1 or 2 (negative because the line is going down)
The intercept in -3 because thats the first place the line touches the y axis.
By verbal reasoning, the pair of words required can be obtained from the
synonyms of the given pair.
Correct response:
- <u>Variable</u>; <u>supposition</u>
<h3>Analysis used for making the above selection</h3>
Prediction: A prediction is a statement indicating the result to be
expected from a trial or test, based on deductive reasoning from a
theory or hypothesis.
An explanation is a statement describing a phenomenon and is taken as
an hypothesis.
A variable is an outcome of a test or trial, or observation.
A supposition is a held notion or belief that is similar to a hypothesis.
Therefore;
Prediction is to explanation as <u>variable</u> is to <u>supposition</u>.
